3 Claims.

Our present invention relates to improvements in textile fabrics andmethod of producing the same, and particularly to fabrics of the openmesh or marquisette type having designs formed thereon by incorporatingat the time of weaving filling threads or roving.

Prior to our invention, fabrics of the above type have been produced formany years with relatively fine warp and weft threads forming the baseof the fabric. The roving, or design filler threads, are relativelyheavy so asto fill the openings in the mesh and form designs onpredetermined areas of the fabric. The usual method of producing thesefabrics is to run shuttles containing the weft or ground picks entirelyacross the lay from selvage to selvage, and at certain times, ac=cording to the setting of the harness, some of the weft threads arefloated entirely across the fabric from selvage to selvage so as not tointerfere with the roving, and afterwards these floated threads areclipped off at the selvage. This results in considerable waste of yarnand does not produce as attractive design as is possible under ourinvention.

W e have discovered that instead of floating the weft yarn entirelyacross the fabric from-salvage to selvage, but by weaving all of theground picks or weft in with the warp except at the areas where theroving is inserted, so that the ground picks will be floated only acrossthe baclr of the roving but woven in with the warp between the ends ofthe design areas formed by the roving, a material Y saving in yarn isobtained and the design stands out much better against the open meshbackground. The improved appearance is due to the fact that the pairs ofroving can float together to make a more compact area and when thefabric is finished the design areas with the weft floated therebehindare more or less puffy. The saving in the yarn is due to the fact thatit is not I1Ew= sary when weaving, in accordance with our invention, tocut off long lengths of floated yarn between the selvages and throw itaway. M- thermore, there is a saving in the time oi the weavingoperation for reasons hereinafter pointed out.

The invention will be better understood after reading the followingdescription in connection with the accompanying drawing, wherein Fig. 1is an enlarged fragmentary plan view of the front 0l,'f8.fie of a fabricembodying our invention;

Fig. 2 is a view taken on the line 2-2 of Fig. 3; and

Fig. 3 is a fragmentary plan view looking at the rear of a portion ofthe swatch of Fig. 1.

In the drawing, the numeral 5 designates the warp threads which, as iswell known, pass through and are manipulated by the harness of the loomto engage the weft threads 6 which, in connection with the threads 5,form a mar uisette or open mesh fabric. The spaces 7 between the groundpicks or weft threads 6 have heretofore been filled by roving .or largerthreads to form designs, and the numeral 8 designates roving threadsinserted in the open mesh of the fabric in known manner. The rovingthreads ll are engaged by such of the warp threads 5 as the set-up ofthe harness determines, and usually there are it two strands of theroving 8 between adjacent ground picks 6 filling the openings 7predetermined distances across the fabric. Part of the roving is floatedand is clipped off after the weaving, so that the completed fabricpresents the appearanceof an open mesh background with filled in areasforming dots or designs thereon.

The numeral 9 designates generally a geo= metrical figure formed on thefabric in accord ance with our invention by the roving strands 10. Itwill be noted that whereas the roving strands 8 occupy a line of spaces7 between adjacent weft threads d, that each pair of roving strands 10forming part of the design 9, occupy two lines of spaces and that theweft thread 11, which is the same in diameter as the thread 6, is wovenin with the warp threads 5 and is also floated behind and between thepairs of roving strands 10. In other words, under our invention, all ofthe weft threads are woven in with the warp threads between the selvagesexcept at the points where those of the weft threads corresponding tothe thread 11 pass or floatover and between a pair of roving strands 10.This permits the rov= ings id to slide together and produces a puflyarea more solid in appearance than where the rovings are inserted in themanner shown in connection with the rovings 8. If the design is formedentirely by weaving the rovings and the weft threads in the mannerdisclosed in connection with the rovings 8, it would be neces sary onalternate picks to float the weft thread entirely across the fabricbetween the selvages and subsequently to shear ofi the entire length oifloated weft threads. It is to be understood, of course, that if thespace between the pairs of rov ings 8 was also filled with roving, thatthe fore-=- going condition would exist, namely, that it would benecessary to float out alternate picks of the weft and subsequentlyshear them off and throw them away. If both of the ground picks havebeen allowed to weave in, then we obtain the space between the rovings 8and the rovings are definitely separated. Under our invention, all ofthe ground picks or weft threads are woven in with the warp threads upto the points where they pass across and between the rovings, and it isonly a relatively short length of the ground pick, under most designs,that is floated out. This floated length of the ground pick beingrelatively short does not have to be sheared oil, does not detract fromthe appearance of the finished fabric, but rather tends to puff thedesign out and to fill in any space which may accidentally occur betweenthe pairs of rovings.

Under the old process, the shuttles must make approximately twice asmany trips across the lay as under our invention in pattern on groundpicks, and, therefore, we obtain in addition to the improved appearanceand saving in yarn, also a saving in time in the weaving operation.

We wish it to be understood that the invention is not limited to theformation of any particular design in the open mesh of the fabric nor tothe use of any particular type or color of roving, and that the figureillustrated in the drawing is purely illustrative. For instance, thelarger figure in the drawing shows an open center, whereas the roving tothe right and left of the main figure are arranged in short parallelstretches, and the invention covers both forms and any other design thatmay be produced so long as the weft threads are all woven in, except atthe points where certain ones are floated across predetermined lines onthe design or between the woven in pairs of roving.

We claim:

1. A textile fabric comprising warp and weft I threads interwoven toform an open mesh base,

filler threads of different character than the weft threads arranged inparallel rows of the open mesh between certain of the weft threads andinterwoven with certain of the warp threads to form designs on thefabric where they fill the openings between the weft threads, and someof the weft threads being floated across and be tween the filler threadsbut also interwoven with the warp threads between the ends of thedesigns formed by the filler threads.

2. A textile fabric comprising relatively fine' warp and weft threadsinterwoven to form an open mesh base relatively heavy, filler threadsarranged in parallel rows of the open mesh between certain of the weftthreads and interwoven with certain of the warp threads to form designson the fabric where they fill the openings between the weft threads, andsome of the weft threads being floated across and between the fillerthreads but also interwoven with the warp threads between the ends ofthe-designs formed by the filler threads.

3. A textile fabric comprising relatively fine warp and weft threadsinterwoven to form an open mesh base relatively heavy, filler threadsarranged in parallel rows of the open mesh between certain of the weftthreads and interwoven with certain of the warp threads to form designson the fabric where they fill the openings between the weft threads, andsome of the weft threads being floated across and between the fillerthreads but also interwpven with the warp threads between the ends ofthe designs formed by the filler threads, there being one pick of theweft woven in with the warp in alinement with the division between eachpair of picks of the filler.
